<upd_detl>Google search didn't turn up any railway gates at all. Instead, the *primary* result is chain-drive motors for opening and closing the kinds of metal shutters that block out ground-level shops when they are closed for business. "opening and shutting machine", if you will... Second results are big metal hand-operated wheels for opening and closing water gates (refs).

There is a name for this product, but it doesn't work well in a vacuum. 
シャッター開閉機 = "shutter operator" (refs are a business website with Japanese and English translations). We can't very well stick "operator" as a gloss though.

daijs has this entry. sankoku does not. 

If you search 開閉機 鉄道, google images *still* doesn't return any legitimate railroad searches.

Clearly [2] is dominant today, and not entirely uncommon. I don't think dropping [1] entirely would be a great loss, but it's in daijs, so [rare] at least.</upd_detl>

<upd_detl>I basically agree with Brian's analysis here. Swapping senses amd converting to [dated].</upd_detl>
